Troubleshooting

Find your problem below. If it is not here, tell us what happened and what you saw on the screen.

Installing

Windows says “Windows protected your PC”. This is SmartScreen. Select More info, then Run anyway. See Install Evaloon Editor.

The download page says the download is not available. No installer is published at the moment. Try again later.

The AI Editor

The panel shows “Connect a model”. No model is connected yet. Select it and pick a provider. See Edit with the AI chat.

“Unlock secure storage”. Open Settings > API Keys and unlock with the master password you made. (This applies to the browser version. The desktop app keeps keys in Windows.)

“No API key configured”. Add a key for the provider that is selected. OpenAI and Anthropic keys are separate. See Cloud keys.

401 or an authentication error. The key is wrong or belongs to another provider. Replace it.

“Model not found” or “unavailable”. Choose a model from the list, or type the exact model ID your account can use.

An edit is waiting for approval. The chat is asking before it deletes something, costs something or changes your captions. Choose Run or Approve, or Reject. Auto-approve (the shield icon) skips these questions.

The AI says it cannot edit, or ignores your request. The model may not support tool use. A text-only model can chat but cannot change the timeline. Pick a model that supports tools.

Something went wrong in the middle of an edit. Select Undo last AI turn. Every reply is one undo step, and Stop rolls back half-finished edits.

Local models

“Ollama isn’t reachable”. Start Ollama and select Check again. See Ollama.

“… isn’t installed” for an Ollama model. Run ollama pull with the model’s name.

“LM Studio isn’t reachable”. Open LM Studio and start its local server. See LM Studio.

LM Studio says the context is too small. Select Reload at 8K.

Edits are slow, or the PC runs out of memory. Try a smaller model, and close the other local model if you run both. Exact guidance is to be confirmed.

Connecting other apps (MCP)

Test connection fails, or Status says Stopped. Keep Evaloon Editor open, then open Settings > MCP again. See Connect Claude Code.

Exporting

Export is greyed out. The timeline is empty. Add media or text first.

The file is too big. Use the Smaller File tab, or Compress video… in the options list.

The export fails or the app slows down. Try a lower resolution or 30 fps, and close other heavy programs. See Exporting your video.

Projects

The app closed suddenly. Your work is saved as you go. On the next start, the app offers to restore your project.
